Karen’s how-to page has a lot of fun projects, like this one, emergency eye glasses – “You can make a simple cardboard version by cutting out a piece of cardboard in the shape of glasses, and using elastic (I’ve used rubber bands) to attach it to your head, or cut out cardboard earpieces. Poke several pinholes in the cardboard, about 1/10 inch (2.5 mm) apart. An easy way to do this is to hold the cardboard up to a bulletin board and use a thumbtack to make the holes.” [via] – Link.
